Stock music app integration with Google music beta

I really like how the music app is infused with other parts of the phone like the car dock and the bedside app. But I don't music stored on the phone because Google music is so great. Anytime I hit play on the stock app it just plays sound effects from games folders. Is there anyway to make it work with Google music, or will there be in the future? Using the remote with the HD dock sometimes controls Google music, but other times it plays the stock music app.
